To be honest, this is why I’ve been of two minds regarding the whole thing.
ActivisionBlizzard needs a complete structural change. That’s not going to happen without someone else acquiring them, which they were seeking out themselves.
That it’s Microsoft who did that kind of sucks, but if not them, it probably would have just been someone like Embracer who’s also currently consolidating a lot of IP. Tencent is another option.
If Sony acquired them, it would have led to the same fight, only it’d be Microsoft complaining.
I understand why Microsoft is probably one of the worse options here, due to Game Pass and having their own console, but I don’t think there was ever going to be a good outcome for everyone here. It was ActBlizz who wanted to sell and it was never going to be a cheap acquisition.
Some other deal would have gone through (and be challenged), and I think people would still have issues with it regarding their market share.
